Originally built in 1965, the Six Mile Creek Dam at Lake Macdonald was raised in 1980 to increase its storage capacity.

Lake Macdonald is located in the Noosa hinterland and is part of South East Queensland’s drinking water supply.

It is an un-gated dam, meaning that when it reaches 100 per cent capacity, water flows over the spillway and safely out of the dam. If you would like to be notified when Lake Macdonald (Six Mile Creek) Dam begins to spill, please sign up to our free dam release notification service.

Seqwater has commenced its Dam Improvement Program to ensure the region’s dams continue to meet national standards. The program will see us upgrade some dams and reduce the water levels of others until such time as upgrade works can be completed.
